c31f3f7f7b common/mlx5: share Verbs device match function
The get_ib_device_match function iterates over the list of ib devices
returned by the get_device_list glue function and returns the ib device
matching the provided address.

Since this function is in use by several drivers, in this patch we
share the function in common part.

The ring management in the idxd part of the driver is more complex than
it needs to be, tracking individual batches in a ring and having null

5f0d54f372 ethdev: add pre-defined meter policy API
Currently, the flow meter policy does not support multiple actions
per color; also the allowed action types per color are very limited.
In addition, the policy cannot be pre-defined.

Due to the growing in flow actions offload abilities there is a potential
for the user to use variety of actions per color differently.
This new meter policy API comes to allow this potential in the most ethdev
common way using rte_flow action definition.
A list of rte_flow actions will be provided by the user per color
in order to create a meter policy.
In addition, the API forces to pre-define the policy before
the meters creation in order to allow sharing of single policy
with multiple meters efficiently.

meter_policy_id is added into struct rte_mtr_params.
So that it can get the policy during the meters creation.

Allow coloring the packet using a new rte_flow_action_color
as could be done by the old policy API.

Add two common policy template as macros in the head file.

The next API function were added:
- rte_mtr_meter_policy_add
- rte_mtr_meter_policy_delete
- rte_mtr_meter_policy_update
- rte_mtr_meter_policy_validate
The next struct was changed:
- rte_mtr_params
- rte_mtr_capabilities
The next API was deleted:
- rte_mtr_policer_actions_update

To support this API the following app were changed:
app/test-flow-perf: clean meter policer
app/testpmd: clean meter policer

To support this API the following drivers were changed:
net/softnic: support meter policy API
1. Cleans meter rte_mtr_policer_action.
2. Supports policy API to get color action as policer action did.
   The color action will be mapped into rte_table_action_policer.

net/mlx5: clean meter creation management
Cleans and breaks part of the current meter management
in order to allow better design with policy API.

2d2cef5d4f net/mlx5: allow multiple flow tables on same level
The driver devices support creation of multiple flow tables.
Jump action can be used in order to move the packet steering
to different flow table.
Table 0 is always the root table for packet steering.

Jumping between tables may cause endless loops in steering mechanism,
that's why each table has level attribute,
the driver sub-system may not allow jumping to table with
equal or lower level than the current table.

Currently, in the driver, the table ID and level are always identical.

Allow multiple flow table creation with the same level attribute.

This patch adds the table id in flow table data entry, while
allocates the flow table, if the table level is same but the
different table id, the new table will be allocated with new
table object id. It supports 4M multiple flow tables on the
same level.

a597ef336f net/mlx5: use mask for meter register setting
ASO (Advanced Steering Operation) meter feature may require
to locate the flow context tag action after the ASO action.
When color register is shared by meter_id/flow_id, it's like:
Bits[0-7] A meter color value set by the HW.
Bits[8-31] A flow id and meter id set by SW.

Currently the tag action for meter writes all the bits
of the meter register, so it will potentially overwrite
meter color when ASO meter action is before the tag action.

Set only 24-MSB-bits of meter register in the meter tag action.

83306d6c46 net/mlx5: fix meter statistics
Currently, packets after meter will be steered to a global policer
table,
which includes green/red color rules for every meter, so as to have
counter statistics of each color in every meter.

There's a bug that all the rules in global policer table are matching
only color criteria, so all packets will be counted to one meter only,
and other meter statistics are always zero.

This patch does these:
1. The rules in policer table matches both meter index and color, so
packet after meter could be counted to the correct meter counter.
2. The meter index and flow index are now sharing the available
register bits dynamically. Meter index starts from lsb, and flow
index starts from msb.

f2ea1b6bcf net/hns3: ignore devargs parsing return
In hns3 PMD, as the handler always return 0, the return value
of a function 'rte_kvargs_process' no need to be checked. But
the API definition has return value, so 'void' could be used
to ignore that.
